“…Therefore, exploring which of the above mentioned processes influenced by different N application rates in changing the pH in soil with plants is worth further study. In brief, our results indicated that the combined influence of roots and the combination of N and Zn enhanced Zn availability via decreasing pH in soils, which was agree with the results of Chen et al (2010) .…”

Nitrogen (N) is critical for zinc (Zn) accumulation in winter wheat grain via enhancing Zn absorption into plant roots. This paper explored a possible mechanism for enhanced absorption of Zn in winter wheat by N combined with Zn application based on the Zn bio-availability in soil. A pot experiment with three N application rates (0.05, 0.2, and 0.4 g kg-1), two Zn application rates (0 and 10 mg kg-1), without and with plants was conducted. The results showed that high N (N0.2 and N0.4) combined with Zn (Zn10) application significantly increased the yield, yield components and Zn and N concentrations in winter wheat shoots and grain. The available Zn concentration in soil with and without plants was increased by N0.2Zn10 and N0.4Zn10 treatment at each growth stage. N0.2Zn10 and N0.4Zn10 treatment significantly decreased the pH in soil without plants but had different influences on the pH in soil with plants, which depended on the different N application rates and growth stages. Meanwhile, N0.2Zn10 and N0.4Zn10 treatment decreased the exchangeable Zn but increased loose organic-, carbonate- and Fe-Mn oxides-bound Zn concentrations in soil without plants. The exchangeable, loose organic- and carbonate-bound Zn concentrations in soil with plants was increased by N0.2Zn10 and N0.4Zn10 treatment at different growth stages. Different rates of N combined with Zn application influenced the proportion of Zn in different fractions in soil with and without plants at different growth stages. At Zn10, N0.4 treatment showed higher yield, N and Zn concentrations in shoot and grain, and available Zn concentration in soil, but lower pH in soil than N0.2 treatment. In addition, soil without plants had higher available Zn concentrations and lower pH than did the soil with plants. There were significant differences in Zn chemical fractions concentrations and proportions between the soils with and without plants at each growth stage. Therefore, combined influence of roots and the combination of N and Zn (especially N0.4Zn10 treatment) improved the bio-availability of Zn in soil via changing the soil pH and promoting the transformation and distribution of Zn in different fractions.

“…Du Laing et al (2009) suggested that decaying plant material caused litter to accumulate and contribute to the binding of metals by adsorption, complexation and chelation. Soils with high organic matter usually bind heavy metals more efficiently (Han, 2007; Chen et al, 2010). However, the overall effect of the presence of soil organic matter on metal mobility and bioavailability depends on their nature of SOM and relative abundance of other minerals in marsh soils.…”

The objectives of this study are to investigate distribution of trace elements and heavy metals in the salt marsh and wetland soil and biogeochemical processes in the Grand Bay National Estuarine Research Reserve of the northern Gulf of Mexico. The results show that Hg, Cd and to some extent, As and Pb have been significantly accumulated in soils. The strongest correlations were found between concentrations of Ni and total organic matter contents. The correlations decreased in the order: Ni > Cr > Sr > Co > Zn, Cd > Cu > Cs. Strong correlations were also observed between total P and concentrations of Ni, Co, Cr, Sr, Zn, Cu, and Cd. This may be related to the P spilling accident in 2005 in the Bangs Lake site. Lead isotopic ratios in soils matched well those of North American coals, indicating the contribution of Pb through atmospheric fallout from coal power plants.

“…Allicin and its derivatives [17,18] have been reported in the foreign patents in antifouling application of coatings. As a kind of natural bioactive substance, capsaicin has broad-spectrum antibacterial activity and is also environment friendly [19]. In this study, based on the molecular structure design principle, the monomer N,N 0 -((2-hydroxy-4,5-dimethylbenzene-1,3-diyl) dimethanediyl) bisprop-2-enamide (HDDE)-containing capsaicin derivative structure with excellent thermal stability and antibacterial activity was prepared in our laboratory.…”

A hydrophobically associating polyacrylamide with double bond P (AM‐MAA‐AMPS‐HDDE‐SA) (PAMAHS) has been synthesized by micellar copolymerization technique in mixed solvents (anhydrous ethanol and distilled water (1:10 by volume)) and characterized. The morphology and microstructure of PAMAHS copolymer observations show the formation of multilayer network‐like stacked structure, and the dissolution property and temperature resistance of the copolymer measurements show that PAMAHS has a good solubility and exhibits unique solution behavior. Due to the hydrophobic associations, the solution viscosity increases sharply when the polymer concentration exceeds a certain value. AFM confirms the existence of the polymer network structure in aqueous solution, and the enhancement of thermal stability of polymer is affirmed through TGA. Compared with the unmodified P (AM‐MAA‐AMPS‐SA) (PAMAS) copolymer, PAMAHS incorporation of capsaicin‐like monomer with biological activity is endowed with excellent antibacterial performance against Escherichia coli and Staphylococcus aureus.
